TPS563210A: Response time of OCL

Hi Zeming,

For the OCP , you can refer page 11 of datesheet for reference . 

TPS563210A is a DCAP VALLEY control , with sensing the inductor current . If the current is above the OCL, it won't initial a new pulse . So this time is within one cycle of clock at most .

Hi ,

As OCP only happens at heavy load , so the frequency/cycle time is almost constant .The response time is very short , you can check the OCP value with deferent inductor value to check the variance . 

And for the response timing , you can refer below fig. 

At the worst case , if the inductor valley just above the OCP limit almost near the next cycle , it will need to "wait" near 1 cycle time . Please note that this is the worst case, and you can still take the EC table value which is already considered this variance .

Hi ,

Yes, it's related with ss time.
